Answer:
D!
Explanation:
Using the formula F = ma, you plug in 4.9 for F (force), and 0.5 for m (mass), then solve for a (acceleration).
Answer:
6.88 m/s
Explanation:
The Conservation of Energy states that:
Initial Kinetic Energy + Initial Potential Energy = Final Kinetic Energy + Final Potential Energy
So we can write

We can cancel the common factor of
which leaves us with

Lets solve for 

Subtract
from both sides of the equation.

Multiply both sides of the equation by 2.

Simplify the left side.
Apply the distributive property.

Cancel the common factor of 2.

Take the square root of both sides of the equation to eliminate the exponent on the right side.

We are given
.
We can now solve for the final velocity.

Anything multiplied by 0 is 0.



Answer:
$28200
Explanation:
Since 1 year has 12 months, 10 years have 120 months.
If one has to pay $235 a month, in 120 months one has to pay $235 done 120 times, which is the product of both numbers:

Answer:
If you are asking the definition here is your answer:--
Explanation:
<u><em>Electrons</em></u> are negatively charged particles that revolve around the nucleus of an atom. In QFT(Quantum field theory) Electrons are vibration of space in the positive energy field.
<u><em>Protons </em></u> are positively charged particles found in the nucleus of an atom held by the strong nuclear force. In QFT(Quantum field theory) protons are also different type of vibration in space in the direction of positive energy field.
